RAPID LEVELPATENTED LEVEL SWITCHES WITH UNIQUE CHARACTERISTICS

* The required length can be obtained simply by cutting the steel rod, using an ordinary pipe cutter; or the switching point can be varied by using a float with through hole allowing the required liquid control point to be modified whenever necessary.* It can be used for dirty liquids, water, petroleum, cutting oils, and tolerates the presence of metal and ferrous particles, since the float does not hold a magnet and is integral with the rod.* One float can operate just one Reed (min. or max. level), or two Reeds (min. and empty and extra max. level) thus meeting the most complex needs.* Total safety since the electrical part is completely separate in the tank side and perfectly sealed with respect to the external side by means of ultrasonic welding and resin coating of the pins.* The nylon-glass body is very strong and very resistant with respect to chemicals, and is ideal as an insulating container for the Reed contacts.* The Rapid Levels come standard with rods suitable for control of a max. measurement of 500 or 1000mm. To obtain specific measurements, refer to the table on the next page.* They can be ordered already arranged for the control of predetermined measurements.

THROUGH FLOAT

On request the float can be supplied with through hole and therefore be positioned in the required position without having to cut the rod (which can therefore be as long as the height of the tank). If necessary, the liquid control point can be subsequently be modified as required by simply moving the float.

RAPID LEVEL” TYPE LEVEL SWITCH WITH 1 FLOAT

ADVANTAGES OF THE RANGE

1- These electromagnetic level gauges in Kits can be obtained in the required length “L” simply by cutting the control rod with an ordinary pipe cutter and press fitting the float in the cutting place (see table for cutting). 2- The control rod can commutate the signal of 1 or 2 Reeds in sequence (with single or exchange contact).3- The float does not hold magnets, therefore the Level can also be used in the presence of dirty liquids or ferrous particles.

RAPID LEVEL” TYPE LEVEL SWITCH WITH 2 FLOATS

* The RL/G2 range has a head which holds two control rods and two floats.* Each control rod can commutate the signal of 1 or 2 Reeds (with single or exchange contact). Each head can therefore contain from 2 to 4 Reeds.* The most suitable system can chosen for each rod.* In case of excessively dense liquids the two floats can be supplied entirely separate from each other to prevent rod 1 from undergoing friction with the float of rod 2.* The minimum distance between the two points to be controlled is 90mm.

“RAPID LEVEL” TYPE LEVEL SWITCH FOR SIDE USE

* This level switch for “side” use is very versatile: like the “RL” range, it can also be used to control the maximum or minimum level and for controlling the minimum plus empty or maximum or overflow.* Unlike the “RL” range, the distance between the 1st and 2nd signal is not fixed, but has an angular value, which gradually increases with the length of the rod.* This gives the designer many choices; in fact, by varying the length “L”, the switching points of the 1st and 2st Reed vary (read on axis 1 and 2).* The Level (see diagram S3) can likewise be used to start a pump (1st Reed) on axis 1; the contact will remain closed until axis 2. On axis 3 there will be the alarm signal (with diagram S4 there will also be the O.K. signal).

LEVEL SWITCH FOR AGGRESSIVE LIQUIDS WITH 1 OR 2 CONTROL POINTS

* The RL/A is suitable for all liquids compatible with AISI 316 stainless steel.* The Rapid Level for aggressive liquids consists of a normal Rapid Level in nylon-glass inserted in an anodised aluminium jacket and fixed at the bottom to a flange that isolates the body from contact with the liquid contained in the tank; therefore only the control rods, the respective stops and the floats (all in AISI 316 stainless steel) remain in contact with the aggressiveness of the liquids on the internal part of the tank.* The flange can be supplied with fixing holes or with 1”1/2 Gas thread connections (only for Levels with one float) and 2” GAS (for all versions).* The float has a through hole enabling its positioning and possible repositioning.* Like the other Rapid Levels, also this model has magnets for activating the Reed contacts located inside the body, and therefore there is no problem with dirty liquids or liquids containing metal or ferrous particles.* For RL/A - G2 the minimum distance between the two control points must be at least 110mm.

LEVEL SWITCH FOR HIGH TEMPERATURES WITH 1 OR 2 CONTROL POINTS

* The Rapid Level switch for temperatures consists of a normal RL with nylon-glass body, inserted in a completely finned (for heat dispersion) anodised aluminium jacket and joined to the fixing flange through an insulating body (teflon).* This combined method of separating and protecting from the heat and dissipating the residual heat by means of a big increase in the radiant surface, allows our Rapid Level to also work continuously up to 200°C without problems for the electrical part contained in the body.* The flange can be supplied with fixing holes or with 1”1/2 Gas thread connections (only for level switches with one float) and 2” GAS for all versions.

MG - Mini GeniusENTIRELY IN PLASTIC MATERIAL FOR SMALL CONTROL UNITS

* EASY TO USEthere are two scales (oil and water) on the rod, that indicate the exact cutting place for obtaining the required switching point.

* SAFEa) the level switch has structural separation of the electrical part from the tank;b) insensitive to dirty liquids and metal particles.

* VERSATILEa) it can have two types of fixing (flange + thread) at the same time;b) the electrical contacts are reversible (N.O. / N.C. in pres.) with an operation of just a few seconds.

* COMPATIBLEall parts of the level switch are made from the same material (nylon-glass /polypropylene-glass), to make chemical compatibility checking very easy.

* CONVENIENTthis level switch is not only the newest and most reliable available on the market from a technical standpoint, but is also the best in terms of quality value for money.

The brand-new MG range is the result over 20 years’ experience in the field of level switches.This product is a happy synthesis of problems solved and universal use... nothing has been left to chance.For dealers, it is the right product to meet the needs of every customer (user).Extreme versatility and reliability are the main features of this “big - little” level switch.

Cutting the control rod.After choosing the scale corresponding to the liquid used (water - oil), cut the control rod with nippers or scissors at the place corresponding to the control level (see level “L”); then join the float to the rod, fitting it in the special seat.

MG - Mini GeniusThe level switch has the electrical part completely separate from the liquid and perfectly protected on the connector side.The result is a safer product.

Production currently provides for the base body with 1” Gas thread (3/4” on request). A flange with 3 holes (Ø55) or 6 holes (Ø70) can be welded to it (see table).

Moreover, by ordering the flanged (3 or 6 holes) level switch the user will also have a 1” Gas thread connection (3/4” Gas on request) available, for further fixing possibilities.

MG range level switches are insensitive to dirt or ferrous particles in the liquid, as there is no magnet on the float and because the float is integral with the rod.

Unlike the other level switches, all the components (body - rod - float - etc.) of the MG series are made from the same material; this makes it very easy to consult the compatibility tables and choose the right material needed.

A main feature of the MG range is reversibility: by shifting the position of the magnet (M) it is possible to have the contact CLOSED IN PRESENCE or CLOSED IN ABSENCE of liquid.

Everything is made even easier by the presence of a label above the body, which makes positioning of the magnet inside the body clear and immediate.

Except for particular cases, it is no longer necessary to order an SPDT exchange contact.

The MG can be ordered in:nylon-glass for use with:

- water- oil- alcohol- vinegar- petroleum- petrol

polypropylene - glass (on request) suitable for:

- distilled water- ethyl alcohol- detergents- soda- benzol

The easiest way to visually monitor the liquid level, without having to drill the side of the tank.

Adjustment is quick and practical: - remove the float that creates a pressure seal with a silicone sheath (version with NBR float) - cut the rod and centring tube with a pipe cutter - refit the float - or it can be ordered already to size.

The float pushes the rod, with an indicator at the top which clearly and accurately shows the level of the liquid.
